NAIL-EXTRACTOR.

Application filed July 20, 1899.

To @ZZ whom, t may concern.

Be it known that I, GEORGE GUINTHER, a citizen of theUnitedStates,residing at Covina, in the countyot Los Angeles and State ofCalifornia, have invented a new and useful Nail- Extractor, of which thefollowing is a specification.

This invention relates to nailextraotors; and it has for its object toprovide a construction adapted for the extraction ot nails and spikes,one embodiment of the invention being provided with a handle in the formof a lever for operatingit, while the second construction has a carrierfor the movable parts adapted for engagement by a crowbar to manipulateit in the drawing of spikes.

In the drawings forming a portion ol' this Y specification, and in whichlike numerals of reference designate corresponding parts in the severalviews, Figure 1`is a perspective view showing the nail-pulling form ofthe invention. Fig. 2 is a perspective view ofone of the jaws. Fig. 3 isa reverse perspective of a cooperating jaw. Fig. 4 is a perspective viewof a second embodiment of the invention adapted for the drawing ofspikes.

Referring now to the drawings, and more particularly to Fig. 1, theinvention comprises two similar jaws 5 and 6, each of which is of arcshape, and which jaws are 'similarly recessed to receive each thecorresponding lugs of the opposite jaw, and when thus assembled tooutline a disk, in one edge of which is an arc-shaped opening formed bya circle lying within the outline of the jaws in part and projectingslightly therebeyond and resulting in the formation of gripping edges 7and 8. The lugs 9 and 10 of each jaw, which are upon themutually-adjacent faces oi' the jaws, are themselves arc-shaped and areof a length somewhat less than the intervening recesses which receivethe opposing lugs. This permits the rotation of one jaw with respect tothe other upon/a common pivot 11, arranged coaxially with the jaws. Eachjaw has extended therefrom a projection 13, the outer end of which is ofa thickness equal to the thickness of the body portion of the jaw, takenthrough one of the lugs, the inner end of the thickened portion beingcurved to coincide with the curvature of the periphery of the jaw, andthus when the jaws are assem- Serial No. 7243531. (No model.)

bled, as shown in Fig. 1 of the drawings, this curved inner end of thethickened portion of the extension lies against the outer periphery ofthe opposing jaw. Thus it will be seen, as shown in Fig. 1 ofl thedrawings, that when the gripping edges 7 and 8 of the jaws are opened totheir farthest extent the diametrically-opposite lugs of each jaw willbe in Inutual engagement and will form a stop in that direction ofmovement of the jaws; also,when the jaws are in this position theprojections of the jaws will lie in a common line diametrioally of thecircular outline of the jaws. The opposite lugs of the jaws are adjacentthe grippingedges 7 and 8, and said edges include portions of theselugs, the degree of extension of said lugs being such that when thegripping edges are separated, as shown in Fig. 1, the opposite end faceof each lug will engage the extension 18 of the opposing jaw. Thus bymanipulation of the jaws upon their pivots 1l the gripping edges may becaused to open and close, the mutual engagement of certain of the lugsof the jaws and the engagement of certain otherlugs with the ex- V16,adapted for the attachment of a handle,

the opposite end of the frame having a fulcrum-block'l? formed thereon,the jaws in their mutually-pivoted arrangement being placed within theinclosure of the frame .and with their extensions 13 pivoted to theframe through the medium of transverse bolts 18, as shown.

In order to manipulate the jaws to separate the gripping edges, apull-rod 2O is pivoted to the outer face of one of the jaws and extendsrearwardly and parallel with the handle, and thus by reciprocation ofthis rod the jaw with which it is connected may be moved, as also theopposing jaw.

In practice the jaws are so arranged within IOO the frame that thegripping edges thereof will lie on the same side with the fulcrum-block17 and that when the gripping edges are separated the extensions 13 willlie in the plane of the frame. Thus the downward movement of the jawswith respect to the frame will act to bring the gripping edges together,and if the jaws be held and the frame be raised the same result willensue. In the operation of the device the fulcrum-block 17 is brought tobear upon the body in which the nail to be drawn is seated, and by meansof the rod 2O the gripping edges are entered beneath the head and inengagement with the shank of the nail. Through the medium of the handlethe frame is then raised, rotating the jaws upon their pivot and causinga further and more intimate engagement of the gripping edges with thenail. Further upward movelnent of the handle will act to draw the nail.

In Fig. 4 of the drawings is shown a construction in which theprojections 23 of the jaws, corresponding to the projections 13 abovereferred to, are not thickened at their outer ends, but are of athickness equal to the body portions of their respective jaws. ASpanner-frame 24 is substituted for the frame 15, said Spanner-framebeing of arc shape and adapted to receive the jaws when in their openposition and from which the jaws are moved to bring the gripping edgestogether. The spanner 24 in its adjusted position lies intermediate theouter faces of the assembled jaws, the extensions 23 of the jaws beingpivoted to the extremities of thelspanner on opposite faces thereof. TheSpanner 24 has an outwardly-extending stem 25, provided with a pluralityof transverse openings 26, adapted for the reception of a lever in theoperation of drawing a spike.

In the operation of the device the jaws are moved to the upward limit oftheir motion, as shown in Fig. 4, and the gripping edges thereof aremanipulated to lie at opposite sides of the upper end of the spike. Thejaws are held down and the Spanner is moved upwardly until the grippingedges enter beneath the head of the spike and are held thereby againstupward movement, when a crowbar or other form of lever is passed throughone of the openings 26 and is then manipulated upon a suitable fulcrumto raise the Spanner. This upward movement of the spanner will cause thegripping edges to withdrawn.

tightly engage the spike and by further upward movement of the Spannerthe spike is It will be readily understood that in practice the outlinesof the jaws may be varied, they may be supported in any suit-able styleof frame, and that any desired material may be used without departingfrom the spirit of the invention.

Having thus described the invention, what is claimed is- 1. Anail-extractor comprising a frame including parallel members separatedby an interspace, a fulcrum-block at one end of the frame, a handleconnected with the opposite end of the frame, gripping-jaws mutuallypivoted and mounted in the frame between the parallel portions thereof,a radial extension upon each jaw, and pivotal connections between saidextensions and the ends of the frame.

2. A nail-extractor comprising two gripping-jaws mutually pivoted, andeach having lugs corresponding in form and arrangement to the lugs ofthe opposing jaw, the lugs of each jaw being separated by recessesadapted to receive the lugs of the opposing jaw, radial extensions uponthe jaws, a frame pivotall y connected with the extensions and movabletransversely of the jaws to actuate them and separate means connectedwith one of said jaws for moving it with respect to the other jaw.

3. In a nail extractor, the combination with a frame, ofmutually-pivoted jaws having gripping edges, extensions upon the jawspivoted in the frame, and separate means connected with one of said jawsfor moving it with respect to the other jaw.

4. In a nail-extractor, the combination with a frame having a blockextending at an langle thereto, of jaws mutually pivoted and havinggripping edges extending on the same side of the frame with said block,extensions upon the jaws pivoted in the frame and separate meansconnected with one of the jaws for moving it with respect to the otherjaw.

In testimony that I claim the foregoing as my own I have hereto alixedmy signature in the presence of two witnesses.
